In conjunction with the messages displayed in the front panel and the message explanations in status codes and error messages, you will be able to choose for yourself when is the right time (for your particular case) to change the HP No. 81 or 83 supplies. The front panel displays the ink level and will tell you when your ink supply is low, very low or empty. This means you have constantly updated information about your HP No. 81 or 83 supplies. Printhead life is warranted to 700 ml of ink consumed. However, on average the anticipated life expectancy of the printheads is two or three times this. This is provided that the printhead is used under normal operating conditions (using HP ink cartridges only) and its "install before date" has not lapsed. However, results vary depending on the print mode setting you use. When you replace the printhead, always replace the corresponding printhead cleaner. © 2002 hewlett-packard company file:///C|/Documents%20and%20Settings/---/Desktop/HP/html/p0053.htm [8/5/2002 3:14:14 PM]
